Why is my Lexus RX300 AC not working?

Possible Reasons for Lexus RX300 AC Not Working
There could be several reasons why your Lexus RX300 AC is not working. Here are some possible causes based on the search results:
1. Refrigerant Leak: When the air conditioner starts blowing hot air, it could indicate a refrigerant leak. Recharging the refrigerant in the AC system is a common first step to restore cooling capacity.
2. AC Compressor Not Turning: If the AC compressor clutch is not turning when the AC is turned on, it could be a sign of a problem. This could be due to issues with the compressor itself or other components like the rotors.
3. Airflow Control Issues: The AC and heat doors in your Lexus RX300 may not be changing the airflow properly, which could be caused by a stuck door. This can affect the distribution of air through the vents.
4. Blower Motor Malfunction: The blower motor is responsible for blowing hot or cold air through the AC vents. If the blower motor stops working due to a fault, the air will not flow out of the vents when the AC is switched on.
It is important to note that these are just possible causes based on the search results. To accurately diagnose and fix the issue with your Lexus RX300 AC, it is recommended to consult a qualified mechanic or Lexus dealership. They will be able to provide a proper diagnosis and recommend the necessary repairs.
